setup for the BKK

Front: Rotora 6pt front with 14in 2pcs rotor (SS line)
Rear: rotora 4pt rear with 14in 2pcs rotor (SSline)

Brake fluid : ATE blue

goin to williow spring on Angel crest, feel the brake is fading for a bit

on the track after 2 lap, brake faded , need to pump the paddel to get brake.

Check the master cyl is good, vacum line is good, brake oil is good..

So what is goin on? any idea?

could that be still little bubble in the brake line? (have this setup for 1 yrs)

Pad problem?

any feedback will be income..

thanks. ..

you know how sad u feel when u r in the track and u cant drive.. and seeing all your freind is having fun...

 

Are your rotors drilled or slotted? What exact pads are you running? When was the last time you bleed your brake fluid?

 

also what fluid are you using

 

flush the fluid like 8000 miles, is the ATe blud dot 4
pad is the H2 from rotora

 

More importantly what was rotor and pad temperature when fade occurred.

Racing Brake fluid should be replace after each use [when if it ever boils][sample at each caliper and measure moisture content].

"The earliest signs of chemical decomposition can often be detected within a year or so, or after 10,000 to 12,000 miles of normal driving. Hard use that elevates brake temperatures and pressures can accelerate the rate at which the fluid additives break down even more."

"To determine the fluid's condition, you have to test it chemically, physically or electronically."
